TikTok creator builderbrigade revealed a big showroom secret: Pottery Barn and other retailers double up their displays, stuffing two or more duvets inside one duvet cover.

Some commenters on the video seemed shocked, while others — especially former retail workers — claimed that this trick was one of the oldest in the book.

To achieve the look for yourself, one obvious way to make your bed look more luxe is to add two lightweight and fluffy comforters inside your duvet cover.

Simply flip the cover inside out or try the viral 'burrito method' and use clips to hold both duvet layers in place before flipping right-side out again.
